For the metal interconnection in foldable displays, bending resistance is essential in addition to heat resistance and low electrical resistivity. The bending resistance of Al-Nd alloy interconnections can be controlled by precipitation of intermetallic compounds. Then, the Al alloy interconnections capable of dry-ething patterning have also been developed.
